Recently, a new magnetic-based core-shell particles
(MBCSPs) were also developed to target skin cancer cells to
deliver chemotherapeutic drugs in a controlled way. These
particles are made up of a thermo-responsive shell of poly (Nisopropylacrylamide-
acrylamide-allylamine) and a core of poly(
lactic-co-glycolic acid) (PLGA) embedded with magnetite
nanoparticles. These shell particles have unique multifunctional
and controlled drug delivery characteristics with an
ability to provide dual drug release mechanisms (a sustained
release of drugs through degradation of PLGA core and a controlled
release in response to changes in temperature via thermoresponsive
polymer shell), and dual targeting mechanisms
(magnetic localization and receptor-mediated targeting) [68].
In vitro studies demonstrated a sustained release of curcumin
from the core and a temperature-dependent release of doxorubicin
from the shell of MBCSPs were observed with no cytotoxicity
to normal fibroblasts [68]. MBCSPs has a great potential
as a platform technology to target, treat and monitor melanoma
for targeted drug delivery and to reduce the side effects
of chemotherapeutic reagents [68].
